python paramiko

　　

paramiko基于SSH连接ssh Server执行操作（SSHClient远程连接，SFTPClient上传下载)

1. pip install paramiko

    

2. 简单示例
   

   import paramiko
   
   
   ssh = paramiko.SSHClient()  # 创建ssh客户端
   know_hosts = paramiko.AutoAddPolicy()  # 创建ssh白名单
   ssh.set_missing_host_key_policy(know_hosts)  # 加载白名单
   ssh.connect(  # 链接server
       hostname='192.168.100.41',
       port=22,
       username='root',
       password='aegis'
   )
   stdin, stdout, stderr = ssh.exec_command('ip r')  # 执行命令
   print(stdout.read().decode(encoding='utf8'))
   ssh.close()

    

3. 结合多线程
   

   from settings import pool
   import paramiko, threading
   
   
   class ParamikoThreading(threading.Thread):
       def __init__(self, host, username, password, port=22, command='ip a'):
           self.host = host
           self.username = username
           self.password = password
           self.port = port
           self.command = command
           super(ParamikoThreading,self).__init__()
   
       def run(self) -> None:
           ssh=paramiko.SSHClient()
           know_hosts=paramiko.AutoAddPolicy()
           ssh.set_missing_host_key_policy(know_hosts)
           ssh.connect(
               hostname=self.host,
               port=self.port,
               username=self.username,
               password=self.password
           )
           stdin,stdout,stderr=ssh.exec_command(self.command)
           print('*'*60)
           print('ip:%s,\ncommand:%s,\n' % (self.host,self.command))
           print(stdout.read().decode(encoding='utf8'))
           print('*'*60)
           ssh.close()
   
   if __name__ == '__main__':
       command='ip a'
       t_pool=[]
       for host in pool:
           t=ParamikoThreading(
               host=host.get('host','localhost'),
               username=host.get('username','root'),
               password=host.get('password','aegis'),
               command=command
           )
           t_pool.append(t)
       for t in t_pool:
           t.start()
       for t in t_pool:
           t.join()

   settings.py
   
   

   pool=[
       dict(host='192.168.100.41',username='root',password='aegis'),
       dict(host='192.168.100.42',username='root',password='aegis'),
       dict(host='192.168.100.43',username='root',password='aegis'),
   ]

    

4. 交互式链接
   

   import paramiko
   ssh=paramiko.SSHClient()
   know_hosts=paramiko.AutoAddPolicy()
   ssh.set_missing_host_key_policy(know_hosts)
   ssh.connect(
       hostname='192.168.100.41',
       username='root',
       password='aegis',
       port=22
   )
   shell=ssh.invoke_shell()
   shell.settimeout(1)
   
   command=input('>>>'+'\n')
   shell.send(bytes(command,encoding='utf8'))
   while True:
       try:
           recv=shell.recv(1024).decode(encoding='utf8',errors='ignore')
           if recv:
               print(recv)
           else:
               continue
       except:
           command=input('>>>'+'\n')
           shell.send(bytes(command,encoding='utf8'))
   
   ssh.close()

    

5. sftp文件upload and download
   

   import paramiko
   trans=paramiko.Transport(
       sock=('192.168.100.41',22)
   )
   
   trans.connect(
       username='root',
       password='aegis'
   )
   sftp=paramiko.SFTPClient.from_transport(trans)
   # upload
   # sftp.put('settings.py','/root/settings.py')
   # download 
   sftp.get('/root/oom.c','oom.c')
   sftp.close()
